The Cloud-to-Thing Continuum: Opportunities and Challenges in Cloud, Fog and Edge Computing

Abstract

Chapter 1 defines the Internet of Things and introduces key concepts and enabling technologies. It provides a sense-making framework that marries technical and socio-technical perspectives and summarises some of the main Cloud-IoT reference architectures. Chapter 2 revisits conventional cloud computing and discusses how cloud computing is evolving as a result of the Internet of Things. It discusses how new processor architectures and service models are changing the essence of what we think of as conventional cloud computing. Chapter 3 tracks the evolution of 5G network technologies. While innovations such as Ipv6 and new paradigms in computing such as fog, edge and dew computing are enabling the IoT, LTE and 5G play a critical role in network connectivity. This chapter explains why RAN designs are critical to 5G success and consequently, the success of the Internet of Things. Chapter 4 review the state of the art with regards to orchestration along the cloud-to-thing continuum with a specific emphasis on container-based orchestration and fog-specific orchestration architectures. Chapter 5 discusses some of the challenges in high-criticality Internet of Things use cases. Storing and processing at the end device (the edge), at the intermediary layer (the fog), or centrally (the cloud) introduces new points of potential failure...
